Is it worth soaking my air filter?

    I realized yesterday that my air filter on the Seca900 is pretty dirty. Most it is actually dirt and debris, but the lower half and front half (so it makes one quarter!) of the filter is soiled by the crankcase vent return, so you could imagine it is a bit oily.

    Should I soak it in hot water with powerful soap, or do I just blow it with the compressor and ignore the old oil? Or should I just replace it with a new one (original part from Yamaha)? I just bought this bike last February from someone who has had the maintenance done by a mechanic, so the PO could not even remember the last time he changed the air filter.

    This said, the filter doesn't look THAT bad, so I doubt it is 10 years old.

    Is 40$ a fair price for a new filter?

    It's a paper filter, so replace it with a new one. They can be had for under $20 from several sources. The $40 one you're looking at had better be a K&N, which is cleanable, and needs to be oiled, but may cause you to need to rejet the carbs.

    Hum, yes, soaking a paper filter would destroy it! The one at 40$ is from a Yamaha parts dealer, so it is an original part.

    What are your "several sources" for under 20$ except ebay?

    E-Bay isn't a source, it's an outlet for sources; as is Amazon.

    Search for EMGO Air Filter 12-94400.

    900 uses emgo 12-94490 and no you will not have to rejet for the emgo nor for most any other paper air filter.

    Thanks for the correction on part numbers. I forgot that the OP was asking about his 900.

    Thank you guys. I will order one soon. All four old spark plugs I removed were sooty black (carbon fouled), I think a dirty air fliter would be enough to cause that, what do you think?

    Ride for a short distance without the filter then check the plugs. Make sure the air filter seats properly when you are putting the cover on. I use a chunk of polystyrene to hold it in place as a safeguard. Crude but effective...

    Thanks. I noticed this filter is a bit tricky to put in back in the right place.
